You're welcome Susan. I still believe that even if they were in USA 4 years that they were birds of a feather - common language and common tradition. One has to think out of the box, what was life like 100 years ago. Was one of them of Byzantine Catholic faith?
The ancestor's church marriage record should provide you with a place of birth as well as parents names.
The English Y is a J sound so Geyza would be Gejza in Slovak.
Requesting Geyza's naturalization intent & petition should provide you with a place of birth. I would not put much into an US census or a death certificate unless it would be an ancestor writing the information.If Slovak is mentioned on the US census than you should consider posting on Slovakia's Genforum.
